As a start..

You wrote, "Now I can not find/open the folders though the files are there". The way I view it, finding a folder and opening a folder could incorporate two separate issues. Given the fact it's Win32/Dorkbot!lnk (found by MSE?), I'm going to presume you mean you're unable to find them, in order to open them.

As a start, I would try the easiest thing first. And that would be to "Unhide files and folders". Also remove the check mark next to " Hide protected operating system files". You haven't included which OS you're running. For: Windows XP / Windows 7.

Best of luck..
